I have an iPhone 15 Pro and it’s around 2 years old and I feel like I should get the battery changed soon. I don’t want to pay Apple 10k for it but I want to get it done from a decent place that’ll calibrate the % and keep everything intact, including water seal and the quality of work done which includes no repaired message. If possible I’d ask them to downgrade my iOS to iOS 17 cus 26 is just horrid in general. Any suggestions or tips for the same would be appreciated, thx :D
